STEP 1:
convert meters to centimeters
100 cm= 1 meter
= 100 cm/m * 2.5 m
= 250 cm
STEP 2:
x= length of first shelf
2x+18= length of second shelf
x-12= length of third shelf
x+4= length of fourth shelf
since the whole board has to be used, add lengths of all shelves and set it equal to the whole length of the board (250 cm).
x + (2x+18) + (x-12) + (x+4)= 250 cm
combine like terms
5x + 10= 250
subtract both sides by 10
5x= 240
divide both sides by 5
x= 48
STEP 3:
find length of second shelf
= 2x + 18
= 2(48) + 18
= 114 cm
CHECK:
x + (2x+18) + (x-12) + (x+4)= 250
48 + (2(48)+18) + (48-12) + (48+4)= 250
48 + (96+18) + 36 + 52= 250
48 + 114 + 36 + 52= 250
250= 250
ANSWER: Shelf two is 114 cm.

Answer:
(47 - 3) * (51-2)
Step-by-step explanation:
Answer:
1/2.
Step-by-step explanation:
Let O = an odd number and E an even number.
The possible outcomes for an odd sum are:
OOO
OEE
EOE
EEO
The probability of an odd on each pick = 50/100 = 1/2 and for an even it is also 1/2.
Prob( O O O) = 1/2*1/2*1/2 = 1/8.
The probability for the other 3 possible outcomes is also 1/8 , therefore the probability for odd number totals = 4 * 1/8
= 1/2.
Answer: 20.5
Step-by-step explanation:
83=4x+1
-1=-1
82=4x
82/4=20.5
x=20.5
Answer:
The length of the two other equal sides must be greater than 3.5 units
Step-by-step explanation:
we know that
The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
Remember that
An isosceles triangle has two equal sides
Let
x -----> the measure of the length of the two equal sides
Applying the Triangle inequality Theorem
1)
therefore
The length of the two other equal sides must be greater than 3.5 units
